HOUSTON, July 10 -- Petrominerales Ltd., Bogota, set production casing to test an apparent discovery in the Llanos basin of Colombia 100 km east of Bogota.

Corcel-1 went to TD 12,000 ft, and logs indicated 140 ft of net oil pay in high-quality sand in the Tertiary Mirador and Barco formations. The deepest interval is to be completed with the drilling rig, and three other intervals will be tested with a completion rig in the third quarter.

The rotary rig will drill a delineation well from the same pad on the 7,918-acre Corcel block. One field near the Corcel block has produced 70 million bbl since discovery in 1981, and another field produced 3.6 million bbl in 1990-2005.

Petrominerales, an 80% subsidiary of Petrobank Energy & Resources Ltd., Calgary, has identified five other prospects on Corcel from 47 sq km of 3D seismic surveys.

Petrominerales plans to shoot 190 sq km of 3D seismic and 576 line-km of 2D seismic overall in 2007 in Colombia, where it holds more than 1.5 million acres on 12 blocks. In 2008 it plans to shoot 3D seismic on its 26,341-acre Guatiquia block, which adjoins Corcel to the south, and drill as many as eight exploration wells, mainly in the Llanos basin.
